The 5 Biggest Mysteries on Serial

Serial is great. Seriously. It's one story told over 12(ish) episodes, and the story featured in the first season is about a murder that happened over 15 years ago. I've heard some people compare it to Dateline, which is sort of true, except that Serial is way better. It's far more in depth, and unlike Dateline where you can say with relative certainty every single time that the husband/ex-husband/boyfriend did it, Serial has presented the case in a way where there is no certainty (at least not at this point). Serial is about halfway through the season and here are 5 questions that must be answered by the end:

{Spoiler Alert, duh.}

1. Who left the anonymous tip? An anonymous tip that encouraged the police to take a closer look at Adnan. Never identified. And none of the characters we've been introduced to so far seem to fit. Except maybe the neighbor boy who knew Jay? Regardless of Adnan's guilt/innocence, it feels like there was another person involved in that day somehow. 

2. How did Mr. S find the body? The guy who was surveying the crime scene nearly stepped on the body because he couldn't see it. How did a janitor who had just downed a forty find it without some sort of tip?

3. Why didn't the defense use Asia? I'm not a lawyer, but alibis are good, right? This girl seemingly has one for Adnan and doesn't appear to have ulterior motives for defending him. So why ignore it in the trial? 

4. Why wasn't the police work scrutinized more? I wasn't there. I don't know everything. But it seems like the detectives gave Jay a lot of leeway in the particulars of his story. And by trial his story mostly, sort of, kind of fit the phone records. And Jay, despite his involvement on the day of the murder, seems to have escaped any sort of scrutiny/investigation. It just seems weird. 

5. Will that lady ever pronounce 'chimp' correctly? The biggest mystery of them all.
